Using the built-in pagination functions

Hi,
I would like to implement the pagination library for retrieving logs from the database.
This is one of my methods in a model:

PHP Code:

    public function getAllLogs(?string $searchString = null, int $limit = 50): array
    {
        $getLogs = $this->db->query("SELECT * FROM `logs` WHERE `string` = ? ORDER BY `insert_date` DESC LIMIT 0, ?", [$searchString, $limit]);

        return $getLogs->getResultArray()?? [];
    } 


Please note that I have edited it a bit to be readable and safe here....
The manual tells me to do this:

PHP Code:

        $model = new \App\Models\UserModel();

        $data = [
            'users' => $model->paginate(10),
            'pager' => $model->pager,
        ];

        echo view('users/index', $data);
    } 


But how does this pagination knows  which method it should call (in my case getAllLogs).
And how can I pass my variable $searchString ?
